SPECIPICATION forming part of Letters Patent N0. 353,442, dated November 30, 1886.

Application filed April 23, 1886. Serial N0. 199,943. (N model.)

T0 all whom it may concern:

Be ib known that I, ROYAL M. CRAWFORD,

a citizen of the United Stabes, residing ab Erie,

in the counby 0f Erle and State of Pennsylvania,have invented eertain new and useful Improvements in Car-Oouplers; and I hereby declare the following to be a ful1, 'elear, and exaeb description of the invention, such as will enab1e obhers skilled in the art1 to which it ap- 1o perbains to n1ake and use bhe same.

'Ihis invention relates t0 car-couplers; and ib eonsists in certain improvements in the 0011- strucoion thereof, as will be hereinafter sei: forth, and pointed out in the claims. My inventaion is illustrated in the accompanying drawings as follows: Figure 1 is a verbical longitudinal seet-ion through the drawhead. on the line y y in Fig. 2. Fig. 2 1's a fronb elevation looking into the thront of the draw-head. Fig. 3 is a horizontal secbion on the line x x in Fig. l. Figs. 4, 5, and6 are views of the slides O and O detached from the draw-head.

A marks the draw-head, whieh is divided into anupper und lower oornparbmenb by a partition, A, and on bhe botton1 of eaeh compartment bhere is a catch-lug, A for engaging the link. The objecb of the two compartments is to enable cars having this drawhead 110 engage ehe links on ears of different heights.

In Fig. 1 I show a link, B, engaged with the catch-lug A in the lower compartment, and in the upper comparbment I show a 1ink 5 just entering Ehe draw-head. This is for the purpose of illustration, as obere will not; be two links in the draw-head at once; bat; where contiguous cars are each provided Wibh my draw-head two links 1nay be used, if it is de- 4o siredto do so.

- In the draw-head, back of t;he eatchlugs A there is a vertical way, A', in whiel1 are adjusted two slides, O C, of whieh 0 extends below Ehe draw-head and is conneclzed wibh a 5 yoke, E, by a pin, E. The yoke asses up ovex the top of the drawd1ead, and may be connected by a stern with levers, plaeed as desired, by which it cztn be raised or lowered, and so raise 01 lower the slides. 'Ihe slide the upper onesets on the lower one, and will be raised as the lower one is lifted, and it can also be raised independe nt of tl1e lower one, as is seen in Fig. l. These slides are also lift;ed by levers D D, whioh are hung ab d d in the mou'ths of the compartments; but; this lifting only ocenrs when a link is pnshed up the incline of the catchdugs A On each 0f the slides, below tl1e link, is a eross-bar, c, whieh, whe n the slides are mised by the yoke E, Will lifb the link up and permit in to disengage from the catchlng.

lt willbe understood frorn the foregoing that: the coupling of ears will be done automatically a-s they are broughb together, Ehe link 011 one entering oho draw-head 011 the obher, and becoming engaged with Ehe cateh- Ing in t;he comparbment ib happens to enter, and thab the uncoupling is effected by liftying the yoke E, whieh liftas the slides and disengages tl1e link from the eatch-lug.

What I elairn as new is 1. In a eareoupler, Lhe con1bination, with Ehe draw-head A, of tl1e eateh-lug A, the slide O, having be cross-bar c, the lever D, pivotzed ab d, and engaging said slide, and the y0ke E, for lifting said slide to clisengage the link from the catch-lug.

2. In a. eanconpler, the combination, With a draw-head, A, having two .comparbmenbs, as shown, of the .cateh-lngs A in eaeh eompartmenb, Ehe slides C and O, each having a eross-bar, c, the levers D D, and the yoke E, fo1 lifing both of said slides, as Set forth.

In testnn1ony whereof I aflix my signature in presence of two witnesses.
